Parshas Tazria/Hachodesh By Rav Moshe Twersky, HY"D

The Medrash says that Klal Yisrael has the ability to impart kedusha onto each month because Ha’Kadosh Baruch Hu imparted kedusha to us. The example for this, the Medrash continues, is klei shareis (the vessels of the Beis Ha’Mikdash): how does the flour and oil of a korban mincha become kadosh? By putting it into a kli shareis. Because the kli shareis is kadosh, it can sanctify other things. Likewise, if you have a vessel which is chullin and you want to make it into a kli shareis, that can be accomplished by placing into it a korban mincha which is already kadosh. Alternatively, a kohein can simply begin using it for avodah and that makes it kadosh. How much more so, then, Klal Yisrael; that they can be mekadeish people, time, and objects.
